Exhibit 10.20

AMENDMENT NUMBER FIVE TO CREDIT AGREEMENT

This AMENDMENT NUMBER FIVE TO CREDIT AGREEMENT (this “Fifth Amendment”) is entered into as of March 22, 2006, by the lenders identified on the signature pages hereof (the “Lenders”), WELLS FARGO FOOTHILL, INC., a California corporation, as the arranger and administrative agent for the Lenders (in such capacity, together with its successors and assigns, if any, in such capacity, “Agent”; and together with the Lenders, the “Lender Group”), BUCA, INC., a Minnesota corporation (“Parent”), and each of Parent’s Subsidiaries identified on the signature pages hereof (such Subsidiaries, together with Parent, are referred to hereinafter each individually as a “Borrower”, and individually and collectively, jointly and severally, as the “Borrowers”), with reference to the following:

WHEREAS, Borrowers and the Lender Group are parties to that certain Credit Agreement, dated as of November 15, 2004, (as amended, , restated, supplemented, or otherwise modified from time to time, the “Credit Agreement”);

WHEREAS, Parent has informed the Lender Group (a) that it intends to restate its financial statements for the fiscal years 2000 through 2004 and for the first three fiscal quarters in the fiscal year 2005 (the “Superseded Financial Statements”) to correct for errors in the application of existing generally accepted accounting principles and for other reasons previously disclosed to the Lender Group, and (b) that the Superseded Financial Statements, and all other quarterly and monthly financial statements of Parent for periods ended prior to the last day of fiscal year 2005 heretofore delivered to the Lender Group (together with the Superseded Financial Statements, the “Pre-Restatement Financial Statements”), should no longer be relied upon;

WHEREAS, Parent has requested that the Lender Group waive any Events of Default that have occurred and are continuing under the Credit Agreement as a result of (a) Borrowers having failed to maintain a system of accounting that enables them to produce financial statements in accordance with GAAP as required by Section 5.1 of the Credit Agreement, or (b) the representations regarding the Pre-Restatement Financial Statements contained in Section 4.11 of the Credit Agreement being incorrect (the “Existing Events of Default”);

WHEREAS, Borrowers have requested that the Lender Group agree to certain amendments of the Credit Agreement and waive the Existing Events of Default, as set forth herein; and

WHEREAS, subject to the terms and conditions set forth herein, the Lender Group is willing to make the amendment requested by Borrowers and waive the Existing Events of Default, as set forth herein.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows:

(iii) Each Protective Advance and each Overadvance shall be deemed to be an Advance hereunder, except that no Protective Advance or Overadvance shall be eligible to be a LIBOR Rate Loan and all payments on the Protective Advances shall be payable to Agent solely for its own account. The Protective Advances and Overadvances shall be repayable on demand, secured by the Agent’s Liens, constitute Obligations hereunder, and bear interest at the rate applicable from time to time to Advances that are Base Rate Loans. The provisions of this Section 2.3(d) are for the exclusive benefit of Agent, Swing Lender, and the Lenders and are not intended to benefit any Borrower in any way.

(vi) Except as otherwise specifically provided in clause (b)(iii) above, payments or prepayments of the principal of Advances shall be applied first to Advances that are Base Rate Loans (with such Advances being deemed repaid in the order in which made) to the full extent thereof before application to Advances that are LIBOR Rate Loans.

(a) Interest Rates. Except as provided in clause (c) below, all Obligations (except for undrawn Letters of Credit and except for Bank Product Obligations) that have been charged to the Loan Account pursuant to the terms hereof shall bear interest on the Daily Balance thereof as follows: (i) if the relevant Obligation is an Advance (x) before the Revolver Increase Date, at a per annum rate equal to the Base Rate plus 2.50 percentage points and (y) on or after the Revolver Increase Date, at a per annum rate equal to the Base Rate or the LIBOR Rate, as the case may be, plus the Applicable Margin and (ii) if the relevant Obligation is the Term Loan A, at a per annum rate equal to the Base Rate plus 2.50 percentage points.

2

(d) Payment. Except as provided to the contrary in Section 2.17(a), the Fee Letter or interest, Letter of Credit fees, and all other fees payable hereunder shall be due and payable, in arrears, on the first day of each month at any time that Obligations or Commitments are outstanding. Borrowers hereby authorize Agent, from time to time, without prior notice to Borrowers, to charge all interest and fees (when due and payable), all Lender Group Expenses (as and when incurred), all charges, commissions, fees, and costs provided for in Section 2.12(e) (as and when accrued or incurred), all fees and costs provided for in the Fee Letter (when due and payable or as and when incurred, as the case may be), and all other payments as and when due and payable under any Loan Document (including the amounts due and payable with respect to the Term Loans and including any amounts due and payable to the Bank Product Providers in respect of Bank Products up to the amount of the Bank Product Reserve) to Borrowers’ Loan Account, which amounts thereafter shall constitute Advances hereunder and, subject to the provisions of Section 2.17 hereof, shall accrue interest at the rate then applicable to Advances hereunder that are Base Rate Loans. Any interest not paid when due shall be compounded by being charged to Borrowers’ Loan Account and shall thereafter constitute Advances hereunder and, subject to the provisions of Section 2.17 hereof, shall accrue interest at the rate then applicable to Advances that are Base Rate Loans.

2.8 Crediting Payments; Clearance Charge. The receipt of any payment item by Agent (whether from transfers to Agent by the Cash Management Banks pursuant to the Cash Management Agreements or otherwise) shall not be considered a payment on account unless such payment item is a wire transfer of immediately available federal funds made to the Agent’s Account or unless and until such payment item is honored when presented for payment. Should any payment item not be honored when presented for payment, then Borrowers shall be deemed not to have made such payment and interest shall be calculated accordingly. Anything to the contrary contained herein notwithstanding, any payment item shall be deemed received by Agent only if it is received into the Agent’s Account on a Business Day on or before 11:00 a.m. (California time). If any payment item is received into the Agent’s Account on a non-Business Day or after 11:00 a.m. (California time) on a Business Day, it shall be deemed to have been received by Agent as of the opening of business on the immediately following Business Day. From and after the Closing Date, Agent shall be entitled to charge Borrowers for 2 Business Days of ‘clearance’ at the rate then applicable under Section 2.6 to Advances that are Base Rate Loans on all Collections that are received by Borrowers and their Subsidiaries (regardless of whether forwarded by the Cash Management Banks to Agent). This across-the-board 2 Business Day clearance charge on all Collections of Borrowers and their Subsidiaries is acknowledged by the parties to constitute an integral aspect of the pricing of the financing of Borrowers and shall apply irrespective of whether or not there are any outstanding monetary Obligations; the effect of such clearance charge being the equivalent of charging interest on such Collections through the completion of a period ending 2 Business Days after the receipt thereof. The parties acknowledge and agree that the economic benefit of the foregoing provisions of this Section 2.8 shall be for the exclusive benefit of Agent.

3

Borrowers and the Lender Group acknowledge and agree that certain Underlying Letters of Credit may be issued to support letters of credit that already are outstanding as of the Closing Date. Each Letter of Credit (and corresponding Underlying Letter of Credit) shall be in form and substance acceptable to the Issuing Lender (in the exercise of its Permitted Discretion), including the requirement that the amounts payable thereunder must be payable in Dollars. If Issuing Lender is obligated to advance funds under a Letter of Credit, Borrowers immediately shall reimburse such L/C Disbursement to Issuing Lender by paying to Agent an amount equal to such L/C Disbursement not later than 11:00 a.m., California time, on the date that such L/C Disbursement is made, if Administrative Borrower shall have received written or telephonic notice of such L/C Disbursement prior to 10:00 a.m., California time, on such date, or, if such notice has not been received by Administrative Borrower prior to such time on such date, then not later than 11:00 a.m., California time, on the Business Day that Administrative Borrower receives such notice, if such notice is received prior to 10:00 a.m., California time, on the date of receipt, and, in the absence of such reimbursement, the L/C Disbursement immediately and automatically shall be deemed to be an Advance hereunder and, thereafter, subject to the provisions of Section 2.17 hereof, shall bear interest at the rate then applicable to Advances that are Base Rate Loans under Section 2.6. To the extent an L/C Disbursement is deemed to be an Advance hereunder, Borrowers’ obligation to reimburse such L/C Disbursement shall be discharged and replaced by the resulting Advance. Promptly following receipt by Agent of any payment from Borrowers pursuant to this paragraph, Agent shall distribute such payment to the Issuing Lender or, to the extent that Lenders have made payments pursuant to Section 2.12(c) to reimburse the Issuing Lender, then to such Lenders and the Issuing Lender as their interests may appear.

(a) Interest and Interest Payment Dates. In lieu of having interest charged at the rate based upon the Base Rate, Borrowers shall have the option (the “LIBOR Option”) to have interest on all or a portion of the Advances made on or after the Revolver Increase Date be charged at a rate of interest based upon the LIBOR Rate. Interest on LIBOR Rate Loans shall be payable on the earliest of (i) the last day of the Interest Period applicable thereto, (provided, however, that, subject to the following clauses (ii) and (iii), in the case of any Interest Period greater than 3 months in duration, interest shall be payable at 3 month intervals after the commencement of the applicable Interest Period and on the last day of such Interest Period), (ii) the date on which an Event of Default occurs, at the election of Agent, or (iii) the date on which this Agreement is terminated pursuant to the terms hereof. On the last day of each applicable Interest Period, unless Administrative Borrower properly has exercised the LIBOR Option with respect thereto, the interest rate applicable to such LIBOR Rate Loan automatically shall convert to the rate of interest then applicable to Advances that are Base Rate Loans. At any time that an Event of Default has occurred and is continuing, Borrowers no longer shall have the option to request that Advances bear interest at a rate based upon the LIBOR Rate and Agent shall have

4

the right to convert the interest rate on all outstanding LIBOR Rate Loans to the rate then applicable to Advances that are Base Rate Loans hereunder.

(b) LIBOR Election.

(i) Administrative Borrower may, at any time and from time to time, so long as no Event of Default has occurred and is continuing, elect to exercise the LIBOR Option by notifying Agent prior to 11:00 a.m. (California time) at least 3 Business Days prior to the commencement of the proposed Interest Period (the “LIBOR Deadline”). Notice of Administrative Borrower’s election of the LIBOR Option for a permitted portion of the Advances and an Interest Period pursuant to this Section shall be made by delivery to Agent of a LIBOR Notice received by Agent before the LIBOR Deadline, or by telephonic notice received by Agent before the LIBOR Deadline (to be confirmed by delivery to Agent of a LIBOR Notice received by Agent prior to 5:00 p.m. (California time) on the same day). Promptly upon its receipt of each such LIBOR Notice, Agent shall provide a copy thereof to each of the Lenders having a Revolver Commitment.

(ii) Each LIBOR Notice shall be irrevocable and binding on Borrowers. In connection with each LIBOR Rate Loan, each Borrower shall indemnify, defend, and hold Agent and the Lenders harmless against any loss, cost, or expense incurred by Agent or any Lender as a result of (a) the payment of any principal of any LIBOR Rate Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any LIBOR Rate Loan other than on the last day of the Interest Period applicable thereto, or (c) the failure to borrow, convert, continue or prepay any LIBOR Rate Loan on the date specified in any LIBOR Notice delivered pursuant hereto (such losses, costs, or expenses, “Funding Losses”). Funding Losses shall, with respect to Agent or any Lender, be deemed to equal the amount determined by Agent or such Lender to be the excess, if any, of (i) the amount of interest that would have accrued on the principal amount of such LIBOR Rate Loan had such event not occurred, at the LIBOR Rate that would have been applicable thereto, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period therefor), minus (ii) the amount of interest that would accrue on such principal amount for such period at the interest rate which Agent or such Lender would be offered were it to be offered, at the commencement of such period, Dollar deposits of a comparable amount and period in the London interbank market. A certificate of Agent or a Lender delivered to Administrative Borrower setting forth any amount or amounts that Agent or such Lender is entitled to receive pursuant to this Section 2.17 shall be conclusive absent manifest error.

(iii) Borrowers shall have not more than 5 LIBOR Rate Loans in effect at any given time. Borrowers only may exercise the LIBOR Option for LIBOR Rate Loans of at least $500,000 and integral multiples of $100,000 in excess thereof.

(c) Prepayments. Borrowers may prepay LIBOR Rate Loans at any time; provided, however, that in the event that LIBOR Rate Loans are prepaid on any date that is not the last day of the Interest Period applicable thereto, including as a result of any automatic prepayment through the required application by Agent of proceeds of Borrowers’ and their Subsidiaries’ Collections in accordance with Section 2.4(b) or for any other reason, including

5

early termination of the term of this Agreement or acceleration of all or any portion of the Obligations pursuant to the terms hereof, each Borrower shall indemnify, defend, and hold Agent and the Lenders and their Participants harmless against any and all Funding Losses in accordance with clause (b)(ii) above.

(d) Special Provisions Applicable to LIBOR Rate.

(i) The LIBOR Rate may be adjusted by Agent with respect to any Lender on a prospective basis to take into account any additional or increased costs to such Lender of maintaining or obtaining any eurodollar deposits due to changes in applicable law occurring subsequent to the commencement of the then applicable Interest Period, including changes in tax laws (except changes of general applicability in corporate income tax laws) and changes in the reserve requirements imposed by the Board of Governors of the Federal Reserve System (or any successor), excluding the Reserve Percentage, which additional or increased costs would increase the cost of funding loans bearing interest at the LIBOR Rate. In any such event, the affected Lender shall give Administrative Borrower and Agent notice of such a determination and adjustment and Agent promptly shall transmit the notice to each other Lender and, upon its receipt of the notice from the affected Lender, Administrative Borrower may, by notice to such affected Lender (y) require such Lender to furnish to Administrative Borrower a statement setting forth the basis for adjusting such LIBOR Rate and the method for determining the amount of such adjustment, or (z) repay the LIBOR Rate Loans with respect to which such adjustment is made (together with any amounts due under Section 2.17(b)(ii)).

(ii) In the event that any change in market conditions or any law, regulation, treaty, or directive, or any change in the interpretation or application thereof, shall at any time after the date hereof, in the reasonable opinion of any Lender, make it unlawful or impractical for such Lender to fund or maintain LIBOR Rate Loans or to continue such funding or maintaining, or to determine or charge interest rates at the LIBOR Rate, such Lender shall give notice of such changed circumstances to Agent and Administrative Borrower and Agent promptly shall transmit the notice to each other Lender and (y) in the case of any LIBOR Rate Loans of such Lender that are outstanding, the date specified in such Lender’s notice shall be deemed to be the last day of the Interest Period of such LIBOR Rate Loans, and interest upon the LIBOR Rate Loans of such Lender thereafter shall accrue interest at the rate then applicable to Advances that are Base Rate Loans, and (z) Borrowers shall not be entitled to elect the LIBOR Option until such Lender determines that it would no longer be unlawful or impractical to do so.

(e) No Requirement of Matched Funding. Anything to the contrary contained herein notwithstanding, neither Agent, nor any Lender, nor any of their Participants, is required actually to acquire eurodollar deposits to fund or otherwise match fund any Obligation as to which interest accrues at the LIBOR Rate. The provisions of this Section shall apply as if each Lender or its Participants had match funded any Obligation as to which interest is accruing at the LIBOR Rate by acquiring eurodollar deposits for each Interest Period in the amount of the LIBOR Rate Loans.

6

“3.4 Term. This Agreement shall continue in full force and effect for a term ending on November 15, 2009 (the “Maturity Date”).

“Base LIBOR Rate” means the rate per annum, determined by Agent in accordance with its customary procedures, and utilizing such electronic or other quotation sources as it considers appropriate (rounded upwards, if necessary, to the next 1/100%), to be the rate at which Dollar deposits (for delivery on the first day of the requested Interest Period) are offered to major banks in the London interbank market 2 Business Days prior to the commencement of the requested Interest Period, for a term and in an amount comparable to the Interest Period and the amount of the LIBOR Rate Loan requested (whether as an initial LIBOR Rate Loan or as a continuation of a LIBOR Rate Loan or as a conversion of a Base Rate Loan to a LIBOR Rate Loan) by Administrative Borrower in accordance with the Agreement, which determination shall be conclusive in the absence of manifest error.
